OJL-BURNER SPECIFICATION forming part of Letters PatentNo: '703,566,dated July 1, 1902. Application filed September 11, 1900. Serial No.29,701. (No model.)

To au w/wm 'z'; may concern:

Be it known that I, ADAM H. FOX, residing at Wissahickon, in the countyof Philadelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Oil-Burners; of which the following is aspecification. r

This invention provides improved means for mixing oil with air or steam,spraying the fluid product, and combining the same with free air in amanner highly advantageousfor securing close and perfect combustion,`affording an exceptional degree of efiiciency as well as a simple,economical, and durable construction.

In the accompanying drawings, Figure 1 is a sectional View of a furnace,showing my invention applied thereto. Fig. 2 is a'front Fig. 1. View ofthe nozzle of my burner, and Fig. 4 is a front elevation of theburner-nozzle.

As shown in the drawings, the burner has a nozzle l with a chamber 2therein and a brancl 3 with the chamber 4 therein communicating 'Withthe chamber 2. The entrance to the noZzle-chamber is connected With anair or stean supply pipe 5, controlled by a Valve 6, and the entrance tothe branch chamber is connected with an oil-supplypipe 7, controlled bya valve 8. The outlet end of the nozzle is provided with the chamber 9,which is separated from the cham'ber 2 by the diaphragm 10, 'having theperipheral -perforations 11 therethrough and'thecone 12 on the innerface thereof.

The burner-nozzle is conveniently supported by the bracket 13, Securedto a channelsection 14:, which is fixed to' the furnace-wall 15, thenozzle projecting through an opening 16 in the channel and into theinwardly-tapering' opening 17 through the furnace-wall. The opening 17,preferably circular in'crosssection, is conveniently'provided bybuilding into the furnace-wall a specially-constructed brick 18, havingthe inwardly-tapering opening 17 formed therein, the bottom of theopening being downwardly in- `clined inwardly in order that any oildeposited thereon may be carried into the furnace. The burner nozzle iseconomically and preferably cast to form from cast-iron and thecylindrical chambers 2, '4, and 9 bored out clean and smooth, leavingthe diaphragm 10 and the cone 12 as integral parts thereof. The holes10, which penetrate the diaphragm at intervals around the base of thecone or peripherally to the diaphragm, are bored out so that their axesare outwardly divergent, and hence the fluid product of oil and air orsteam mingled in the chamber 2 is dispersed not only by the cone 12, but'also by the divergent apertures ll. Any oil that may deposit from the-fluid passing through the apertures 11 is collected 'by the' chamber 9and Vaporized by being drawn into the stream of spray ejected throughthese apertures.

In operation the quantity of oil required is permitted to 'dripregularly through the passage orchamber 4 into the current ofair,preferably, or steanfloWing under the necessary pressure'through thepassage or chamber 2, by which the oil is dispersed and mingled with theair or steam. The fluid product `thus formed is spread by the cone 12and ejected through the apertures ll in diverging streans of spray intoand through the inwardly-tapering aperture 17 through the furnace-wall.This action draws in free outside air through the opening surroundingthe burner-nozzle,- which free air combines with theyaporized productejected through the nozzle, effecting close and perfect combustion andproducing a flame of uniform and high temperature This burner isspecially free from tendency to clog, permitting the use of crudeunfiltered fuel-oil, and is constructed so that any clog or obstructionmay readily be removed.

Having described my invention, I claim- 1. A burner comprising anozzlecontaining a miXing-chamber, a diaphragn consttuting one end of themiXingchamber and having a conical face and peripheral perforations, acontrolled inlet-pipe closing the other end of the mixing chamber, foradmitting air or stean into the mixing-chamber, and a controlledinlet-pipe connected to a port of the nozzle in front of the air orsteam port for admitting oil to the mixing-chamber, substantially as andfor the purposes set forth.

`2Q Aburner conprising a nozzle containing a mixing-chamber, an integraldiaphragn constituting one end of the mixing-chamber IOO and having aconical face and outwa'dly-divergent pe'iphe'al perforations, :inintegral, open chamber exterior to the diaphragn, a controlledinlet-pipe closing the other end of the nixing-chamber, for adnittingair or steam into the mixing-chambe', and a controlled inlet-pipeconnected to a port of the nozzle in front of the air or steam port foradmitting oil to the mixing-chanber, substantially as and for thepurposes set fo'th.

3. A burne' conp'isinga nozzle containing :L mixing-chamber, a diaphragmconstituting one end of the miXing-clamber and having a conical faceand. peripheral perforations, a controlled inlet-pipe closing the otherend of Witnesses:
